Abstract

Apparatus and an associated method for notifying communication stations of communication allocations made to communicate data. A matrix representation is formed of communication resources that are allocated for communication of the data. The matrix representation is used to construct an assignment bit map by a bit map constructor that is representative of the allocated communication resources. And, a temporary flow set identifier generator is used to form a temporary flow set identifier. The temporary flow set identifier includes the assignment bit map as a portion thereof.

Claims

1. Apparatus for providing notification of an assignable communication resource allocation for communication of data in a multi-carrier communication system, said apparatus comprising:

a bit map constructor adapted to receive a representation of the assignable communication resource allocation made for the communication of data during a communication session in the communication system, said bit map constructor configured to construct the at least one assignment bit map during said communication session; and

a temporary flow set identifier generator adapted to receive the at least one constructed assignment bit map, said temporary flow set identifier generator configured to generate a first corresponding temporary flow set identifier, the first temporary flow set identifier including the at least one assignment bit map, the temporary flow set identifier for communication during the communication session to provide the notification of the assignable communication resource allocation re-allocation during said communication session, for the communication of the data.

2. The apparatus of claim 1 further for providing notification of a second assignable communication resource allocation during said communication session for communication of data, said bit map constructor further adapted to receive a second representation of the second communication resource allocation said bit map constructor further configured to construct a second assignment bit map.

3. The apparatus of claim 2 wherein said temporary flow set identifier generator is further configured to generate a second temporary flow set identifier including the second assignment bit map, the second temporary flow set identifier for communication to provide the notification of the second assignable communication resource allocation.

4. The apparatus of claim 1 wherein the first temporary flow set identifier comprises an extension to a temporary flow identifier.

5. The apparatus of claim 1 wherein the data is communicated pursuant to a multicast communication service, the first temporary flow set identifier providing the notification of the first assignable communication resource allocation for the multicast communication service.

6. The apparatus of claim 1 wherein the first temporary flow set identifier further comprises a starting indicia identifying when the first assignable communication resource allocation commences.

7. The apparatus of claim 6 wherein the starting indicia comprises an implicit starting indicia implicitly identifying when the first assignable communication resource allocation commences.

8. The apparatus of claim 1 further comprising a transmitter adapted to receive the first temporary flow set identifier, said transmitter configured to transmit the first temporary flow set identifier upon an overhead broadcast channel.

9. The apparatus of claim 8 wherein the overhead broadcast control channel upon which said transmitter transmits the first temporary flow set identifier comprises a packet broadcast control channel.

10. The apparatus of claim 1 wherein said temporary flow set identifier generator is further configured to generate the temporary flow set identifier at selected intervals.

11. The apparatus of claim 10 wherein the temporary flow set identifier, when generated at a subsequent selected interval, comprises an updated first temporary flow set identifier.

12. Apparatus for receiving notification of an assignable communication resource allocation in a communication station operable pursuant to communication of data in a multi-carrier communication system, said apparatus comprising:

a detector configured to detect a temporary flow set identifier delivered to the communication station during a communication session with the communication station, the temporary flow set identifier including at least one assignment bit map, the at least one assignment bit map representative of a first assignable communication resource allocation re-allocation during-the communication session; and

a controller adapted to receive an indication of detection made by said detector, said controller configured to control operation of the communication station responsive to detections made by said detector.

13. The apparatus of claim 12 wherein said detector is further configured to detect an update of the temporary flow set identifier delivered to the communication station, the update to the temporary flow set identifier including at least an update to a first assignment bit map.

14. A method for providing notification of an assignable communication resource allocation for communication of data in a multi-carrier communication system, said method comprising the operations of:

constructing at least one assignment bit map during a communication session, responsive to the at least one assignable communication resource allocation;

generating during the communication session, at least one temporary flow set identifier including the at least one assignment bit map, the first at least one temporary flow set identifier for communication during the communication session to provide notification of the assignable communication resource allocation re-allocation during the communication session, for the communication of the data pursuant to the at least one temporary flow set.

15. The method of claim 14 further comprising the operation of transmitting the first temporary flow set identifier upon an overhead broadcast channel.

16. The method of claim 15 wherein the overhead broadcast channel comprises a packet broadcast control channel.

17. The method of claim 15 wherein the first temporary flow set identifier generated during said operation of generating further comprises a staffing indicia identifying when the first assignable communication resource allocation commences.

18. The method of claim 15 wherein the first temporary flow set identifier transmitted during said operation of transmitting is transmitted to a remote station.

19. The method of claim 18 further comprising the operation, at the remote station, of detecting delivery of the first temporary flow set identifier.

20. The method of claim 19 further comprising the operation of controlling operation of the remote station responsive to the first temporary flow set identifier.
